MEANS FOR SECURING BEDSTEAD-SPINDLES.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed November 3, 1909. Serial No. 525,997.

To all whom it may concern:

Be it known that I, JOHN C. WILSON, a resident of Kenosha, in the countyof Kenosha and State of WVisconsimhave invented certain new. and useful Improvements in Means for Securing Bedstead-Spindles, of which the following is a full, clear, and precise specification.

My invention relates to improved means for securing spindles to their supporting members in metallic bedsteads.

In bedsteads, particularly brass bedsteads, vertical spindles are connected between horizontal supporting members of the head and foot framesof the bedstead. In the spindle ends threaded 'pieces or nuts are usually secured for receiving stay pins or screws. In the prior art the ends of the spindle have been indented and rendered irregular to form supporting and securing means for the nuts, this construction hinderin to a great degree proper and uniform bufli ng and lacquering of the spindles. Furthermore, the irregularities extend a considerable distance inwardly ,from the spindle ends, thus requiring comparatively large trimming or finish pieces.

Among the salient objects of my invention are to provide a construction in which all indentures and irregularities are eliminated which I results in a smooth, uniform and straight'outer surface for the spindles which can t us be more easily and uniformly bufi'ed and lacquered; toprovide a construction which limits the attachment of nuts to the extreme ends of the spindles whereby trimming or finish pieces, if used, need be very small; to prov1de a construction in which the method of securing the nuts to the spindle ends will result in concave ends which will snu ly receive curved supporting members to Fock the spindles against rotational dis lacement and to eliminate the necessity of ish pieces; to provide a construction in which nuts can bemore uickly, more accuratel and more secure y applied to the spin les with little labor; and in general to provide a construction and arrangement which will securely and rigidly hold the members together with a minimum number of arts and which will present a finished an neat appearance.

My improved construction and arrangewhich drawin Figure 1 is an elevation view of sections of upper and lower horizontal sup orting members connected together by a indle, the upper part of the spindle and the top supporting member being in diametral section, Fig. 2 is an elevation view of the parts shown in Fig. 1, showing a somewhat modified arrangement of connecting the spindle with the lower supporting member, Fig. 3 is a sectional view taken on plane 3-3, Fig. 1, Figs. 4, 5 and 6 show in detail the construction of a spindle, Fig.. 4. being an elevation View of the spindle, and Figs.

5 and 6 upper and lower end views respec-- tively Fig. 7 is a plan view of the inner side of a nut which I employ, Fig. 8 is an end view of the nut, Fig. 9 is an end view of the spindle showing a nut secured thereto, Figs. 10 to 15 show the parts of Fig. 1 but separated, Fig. 10 showing the top supporting member with a finish piece thereon, Fig. 11 showi the spindle with the nut attachments, ig. 12 showing a finish piece for the lower end of the spindle, Fig. 13 showing the lower supporting member and Fig. 14.- showing a screw for passing through the lower supporting member into engagement with the nut at the lower end of the spindle, and Fig. 15 is a plan view of the under side of the finish piece shown in elevation in F ig. 12.

Referring to Figs, 4, 5 and 6, the spindle 1 is shown in the form'of a tube having diametrically opposite slots 2 and 3 out into its upper end and similar slots 4 and '5 cut in its lower end.

Referring to F i s. 1, 7 and 8, the nut 6 has a rectangular ody part 7 whose edges 8 and 9 are curved to a radius equal to. the inner radius of the spindles, and these edges have short projections 10 and 11 whose radius is equal to the outer radius of the spindles. During formation of the nut the body part is slightly arched, as shown in Fig. 8 and the ends 12 and 13 are bent at right angles, this construction giving the nut great strength to prevent longitudinal flexure thereofwhen the spindles are a plied to the support members. At t e center of the nut is a. t eaded opening 14:.

spindle ends-with the'nut en cured in p The projections 10 and 11 of the nuts have the same width as the slots cut in the spindle ends and when the nuts are a plied to the s 12 and 13 extending inwardly these projections engage in the slots and the edges 8 and 9 engag; the inner surface of the spindle, thenuts ingthus securely held in place. The ends or ints 15' of the end sections15 between t 0 slots are now turned inwardly against the nut, pressure at the same time being applied to the nut so that the archis taken out of the rojections 10 and 11, and these projections ecome strai ht to snugly engage the bases of the spind e slots. The nuts .are thus firmly and accurately locked in place with their openings 14 at the center of the spindle.

Into the upper nut of each spindle is threaded a stay pin 16 which upon assembly enters an opening 17 in the top supporting member 18, as shown in Fig. 1. The lower ends of the spindles abut a ainst the lower supporting member 19 an are seace by a screw 20 passing through openings 21 in the lower member and into the lower spindle nuts. The screws may have shanks of cheaper material and a separate head 22 of ornamental material. The inturned ends 15 and the nuts form concave pockets 23 which snugly receive-the sup ortmg members and asslst in securely ho ding the spindles in position. The end sections 15 instead of having their points 15' bend abru tly inward can be gradually bent inwar y from a central point so that the resultant edges 24. are semi-circular to closely fit the supporting members, as shown in Fig. 2. Where this construction is used the nuts are preferably of the same material as the spindles so that a finish connection will result without the necessity of special finish or trim pieces. After turning over of the ends 15 to clamp the nut the ends and the nut face can also be und to resent a more regular cylindrica tpocket wliieh will more accurately receive e su portingmembers. When the construction s own in 'Fig. 9 is used or where further finish or trim is desired suitable finish pieces can be applied.

As shown in Figs. 1, 3, 12 and 15, a finish iece in the form of a ferrule 25 is provided for the connection of the spindles with the lower supportin member 19. This ferrule comprises a cylimIi-ical sleeve 26 having a concave cylin rical floor 27 .provided with a vcentral opening 28. The ferrules are slipped overthe lower ends of the spindles, the screws 20 passing through openin 28, and the cylindrica concave bases of the ferrulesengaging intimately with the tubular sup 'orting member, so that a perfect fit and fims is secured. In the connection between the upper ends of the spindles and the upper supporting members, as shown, the

member and eaaoea spindles are not ri 'dl held to the supporting member and a nis member is desirable. This finish member ma be in the form of a spherical shell or hus 29 which has side openings 30 for receiving the supporting a lower opening 31 for receiving a spindle. The same attachment asthat used for the lower spindle ends with the lower supporting member could of course be used for the upper spindle ends with the upper su porting members, the pin 16 in this case eing replaced by a screw 20. The threaded pin 16 instead of passing freely through opening 17 could have threaded engagementwith this 0 enin so that the upper end of the spind e cou d be rigidly secured to the supporting member.

- In the construction and arrangement which I have shown and described only the extreme ends of the spindles are utilized for securin the nutsin place and the outer surface 0 the spindles remains. smooth and straight and can thus be very readily and uniformly buffed andlacquered, there being no indentures or irregularities'which would be a. hindrance to bufling and lacquering.

The process of securing the nuts in position concave spindle ends automatically results in orting memwhich snu ly receive the sup to the supporting member centers so that if finish or trim p eces are desired they need be very small as compared with trim pleces necessary in prior constructions. Furthermore, by a slightl modified arran ement the concave ends wil so snugly an securely engage the supporting members that trim pieces will be unnecessary. These concave ends also prevent rotational displacement of the spind es thereby reventing loosening of the screws. The entire bedstead with'my arrangement will present a very neat and substantial appearance. 7

Having thus described my invention and its various desirable features, I desire to secure a the following claims by Letters Patent.
